Events incorrectly saved after dragging on day & week view

Good day,
I have noticed a possible bugs with the Calendar application.
The initial saving of an event is OK. However, when I drag the event on the calendar to another time, it does not save correctly. [LIST=1]

  • Created an event for 10 am
  • Dragged the event to 1 pm. The event is then auto saved to 10 pm instead
  • Then dragged the event to 2 pm. The event is then auto saved to 11 pm [/LIST] What causes this behaviour? Is it perhaps linked to regional setting problems?
